UV-Vis 20161012Sample PreparationDataThis figure displays the UV-Vis absorbance of our Fructose concentration 0.125 mM pH 4-12 solutions over a spectrum of wavelengths. pH 11 and 12 have the highest absorbance in the area of interest, however there is no distinct peak for either solution. This figure displays the UV-Vis absorbance of our Fructose 0.25 mM pH 4-12 solutions over a spectrum of wavelengths. pH 4, 11, and 12 have the highest absorbance in the area of interest. The absorbance obtained from pH 11 and 12 display potential peaks around 400 nm and 500 nm, respectively, however there is no distinct peak for the pH 4 solution. The figure above displays the Absorbance at peak wavelength 530 nm for our Ag NP pH4-12 Fructose concentration 0.125 mM. pH 11 and 12 have the most significant absorbance. pH 10 is not that much lower. pH 4 is the lowest we have observed it in any of our Ag NP UV-Vis experiments (thus far). The figure above displays the Absorbance at peak wavelength 530 nm for our Ag NP pH4-12 Fructose concentration 0.25 mM. pH 4, 11, and 12 have the highest absorbances observed in this experiment. Absorbance of pH 4 is significantly higher than pH 11 and 12. |
